Synology walks back controversial compatibility policy for 2025 NAS units — third-party HDD and SSD support returns with DiskStation Manager 7.3 update

The Synology DiskStation DS925+ and DX525 NAS units placed on a desk.

Synology has backtracked on its controversial self-branded drives-only policy, restoring the ability to use third-party and certified HDDs and SSDs on its 2025 Plus series NAS units. With the launch of its latest DiskStation Manager 7.3, users can once again use 3.5-inch hard drives and 2.5-inch SATA SSDs from brands like Western Digital and Seagate, without losing out on crucial features.

Earlier this year, the company had restricted core functionality for third-party and non-certified drives, including support for storage pools, health monitoring, deduplication, and firmware updates. The company made Synology-branded and Synology-certified drives compulsory, claiming that users of the Plus series NAS models would benefit from higher performance, increased reliability, and more efficient support.

In a way, the company forced users to rely solely on Synology-branded disks to unlock full capabilities. This reportedly resulted in community backlash, which eventually allowed rival brands to take advantage and promote their own hardware as more open and flexible alternatives.
